Oil filter, buying one at Lexus vs Toyota dealer . . . .

Vrank, good to know. I've never used Napa Gold filters, but I've seen them recommended a few times on various forums. I was planning on going with Toyota filters to eliminate the guesswork of what aftermarket item is up to OEM spec, but if the Napa Golds fit the bill, they're a little bit cheaper and more convenient for me to pick up, so I might as well go that route. FIL 1348 is the part # for the SC400, BTW.

We (Toyota dealer) buy those filters by the cases nearly every day and I can assure you that is a false statement. The D1 filter was superceded by the G1. If you find D1's it is old stock.

G1 filters are made in the US. D1 filters are made in Thailand. If you look in the D1 filter you will see a check valve clearly visible. A G1 doesn't have a visible check valve. If you look at the G1 box it tells you what engines it's supposed to be used on. You won't see a 2jz on that list. That being said, both filters are F-08 filters so they will both work without problem. If you look up a filter in the Lexus catalog, It says to use the D1. D1s aren't old stock just different manufacturers. D1s are shipped in boxes of 10' and G1s are shipped in boxes of 12. I personally use D1s just because that's what they recommend.

It says JZ series on the front of the G1 box. Only differences are the D1 is bought in bulk and comes prelubed on the o-ring from the factory.

G1s are ordered in quantities of 12 while D1s are ordered in boxes of 10. It doesn't matter how many toyota orders, they will just be in boxes of 10 or 12.When I looked at the 2 filters, the G1 is actually the one with the visible check valve.

I'm a tech at a Toyota dealer here in KC, and when i mean bulk i mean when the parts department orders filters they order them by the hundreds maybe thousands. That is bulk, not by how many are in a box.
And the D3 is the filter that the UZ family of V8s take. I think only difference is that it has more oil capacity than the D1/G1

I understand what you mean by bulk. I'm in South Carolina. This is the south eastern region for Toyota. I do stock orders for Toyota all the time. I always order filters in bulk. It's not because I have to, it's because it doesn't make sense to order 10 or 12 filters when we sell hundreds of filters in a day.
